Sen. Lindsey Graham is making his final television ad pitch with two spots that remind voters that he’s a diehard conservative.

Graham is trying to get a majority in Tuesday’s Republican Senate primary, and the latest Clemson University Palmetto Poll showed him with 49 percent. If he fails to get more than 50 percent, he’d compete against the runnerup in a runoff two weeks later.

Tea party activists have criticized Graham for not adhering strictly to conservative principles; the new ads try to refute that argument.

His campaign said the ads are “part of a significant six-figure statewide ad campaign running on television, radio, and digital platforms.”

In the spots, he “humbly” asks for South Carolina Republicans’ votes.

They then list what he’s done, including support for building the Keystone XL Pipeline “as part of an â“all-of-the-above” effort to reduce our dependency on Middle Eastern oil, “Opposition to Obamacare from Day One and fight to repeal, replace, and opt-out of it” strong efforts to “find answers on what happened in Benghazi,” and “standng up for our military and providing our troops and veterans the equipment and services they need.”
